4 Claims. (Cl. 128-395) This invention relates generally to light-raytreating devices and especially to a structure adapted for irradiationlby so-called sun lamps, and wherein the irradiation treatment isVaccomplished by exposing the face of the seated personto the rays ofsuch sun lamps.

While irradiation devices are well known in the art, the presentinvention contemplates a simple, inexpensive and most eiective light-raytreating device which can be readily assembled and placed almostanywhere and which can be as readily disassembled for packaging andtransportation.

It is further contemplated that when the device is assembled, erectedand is made ready for use, it will facilitate the placement into properposition of a seating unit, such as a chair, and wherein theray-emanating lamps are so disposed that they permit unrestrictedpassage of a person to and from the chair placed in proper relation tothe lamps.

The prime object of this invention therefore is the provision of areadily assemblable, simple, inexpensive but elective portable light-raytreating device so constructed and arranged, that a mobile seating unitfor a person to be treated can be placed in proper position forirradiating such persons face, and which device has at least one pair oflight-emanating lamps so disposed that their light rays converge towardthe face of the person seated upon the unit, and wherein the lamps areso arranged that they permit ready passage between them f a personmoving towards or from the seating unit.

A further object of this invention is the provision, in conjunction withthe aforesaid treating device, of a coincontrolled timing device withineasy reach of the person seated facing the lamps, and which timingdevice is adapted to govern the supply of electric current to the lamps,as well as the length of time of the treatment.

The foregoing and further objects and advantages of the presentinvention will become more fully explained from the ensuing descriptionin conjunction with the accompanying drawings, wherein:

Fig. 1 is a perspective illustration of one form of the device inaccordance with the present invention;

Fig. 2 is an enlarged partial section taken approximately along lines 22 of Fig. l;

Fig. 3 is `a partial enlarged section taken approximately along lines3-3 of Fig. l;

Fig. 4 is a partial enlarged section taken approximately along lines 4 4of Fig. l;

Fig. 5 is an enlarged section taken along lines 5 5 of Fig. l;

Fig. 6 shows a perspective view of a modified form of the device;

Fig. 7 illustrates a perspective view of a third modication of thedevice; and

Fig. 8 is a perspective view of the simplest form of the device.

In each of the Figures 1, 6, 7 and 8 are shown seating units, such aschairs, indicated in broken lines, and which chairs are placed at properrelation to the lamps.

Describing Figs.- l to 5 in detail, numeral 10 denotes a-substantiallyU-shaped frame composed of two parallel channels 11V and 11' andavconnecting channel 12. Channels 11 and 11 and channel 12 are securedtogether by corner pieces 13.

Extending from the ends of channel 11, 11' are uprights 14 supportingsun lamps 15. From about the center of channel 11 extends anotherupright 16 adapted for the support of a coin-controlled timer 17.

U-shaped base 10 is so arranged asto permit the placementi within itsconfine of, a chair 18 in such a position that when a person is seatedthereon and a coin isdropped into the timer to energize sunlamps 15, therays from the lampswill strike the persons face. inasmuchV as the timeof exposure to sunrays necessarily must be limited, timer 17 is soarranged that after a predetermined time period it cutsiofl" the currentsupply to the lamps.

As seenV inFigs. 1' to 5 theA base is constructed from channels whichfacilitate ready wiring. In Figs. 2 and 3 is indicated the manner bymeans of which uprights 14 supporting lamps 15 and upright 16 for timer17 are connected to channels 11 of base 1t). lt will be noted that fromchannels 11 extend internally threaded cylindrical sleeves or couplings19 which are preferably welded to channels 11 at 20. The internalthreads of the couplings are engaged by the external threads of bushings21, while the internal thread of the bushings engage the threads ofuprights 14. and 16. Obviously any `other convenient form of connectingthe uprights with the base can be employed.

The connections between the base and the uprights are intended tofacilitate ready assembly and disassembly of the device. For the samepurpose there are also provided electrical connections in the form ofplugs and receptacles for the conductors to lamps 1S and timer 17. Theseplugs are indicated in Figs. 2 and 3 at 22 and 22 and the correspondingreceptacles are denoted at 23 and 23. It is preferred that the ballastsfor lamps 15 are conveniently housed within the relatively broad channel12, one of the ballasts being indicated at 24 in Fig. 4.

In Fig. 6 is shown a structure very similar to that of Fig. 1, whereinhowever the connecting channel 25 is placed in the front while the twoparallel channels 26 and 26' joined by the connecting channel aredirected rearwardly. The lamp-supporting uprights 27 and 27 extend fromthe two parallel channels and timer 17' is suspended from an angularstructure 28 which extends from channel 26 in upright direction andcontinues as la horizontal arm 29, the latter being connected at 30 withupright 27. In this modification the chair 18 is placed into the openend of the U-shaped base. A person seated upon the chair will receiveirradiation at his face from lamps 15.

In the modified form shown in Fig. 7 there is employed instead of aU-shaped frame, a platform 31 which forms the base of the device.Extending from that platform are uprights 32 and 32 for supporting lamps15, upright 32 in addition accommodates timer 17". Platform 31 isadapted to support a chair or the like 18".

In Fig. 8 another modification is shown which is of the simpleststructural form, wherein a channel-shaped `base 33 is employed and fromwhich extend uprights 34 and 34' for mounting lamps 15. To upright 34timer 117 is attached. Chair 118 is placed so that the rays from thelamp are directed toward the face of a person seated on the chair.

All the aforedescribed devices are substantially of "a commonconstruction in that they all have what is termed herein as a base anduprights to support the lamps, and wherein all of the uprights and thelamps are so disposed Patented.A M8414-, 1958.`
